rate. The same is a good station for Cijdippe, and Beroe, and Medusa ; 

 and the shore and walls are most productive, in great variety, A large 

 shabhy-looldng Cydippe is very apt to be " in spawn," and the ova will 

 Jioat, visible to the naked eye, and may be mistaken for Noctiluca (see 

 Remains, " Beroid Babies.") A rushlight shews such objects extremely 

 well. — Our kind regards to all. Yours truly, J. Price. 



These lineB will elicit heartfelt admiration and sympathy 

 in all who know the painful circumstances under which they 

 were written. 



Mr. Price regards Cydippe as the most beautiful of all 

 invertebrate living things. When Cydippe is seen in perfec- 

 tion, the writer is quite inclined to agree with the estimate of 

 Mr. Price, who adds : — 



I never saw Beroe take any food but Cydippes, nor Cydippe any 

 but a very ghost-Uke Shrimp with staring eyes {My sis ?), refusing 

 other Crustacea. Two large Cydippes were dissolved away in four and 

 a quarter hours, and then replaced by two others. Cydippes may be 

 often taken with the vessels full of a milky fluid, which shews the 

 further process of digestion admu'ably. The Beroe is too flimsy to 

 shew this so well. The trains and ciha work briskly after being 

 swallowed. Query — How can the Beroe bite a hole out of the Cydippe 

 when too large to bolt ? — See Remains.
